実験手順

The procedure is analogous to that described in Example 23, but 3.1 g of N-[2-oxo-2-(1,2,3,4-tetrahydro-1-quinolyl)ethyl]-N-phenyl-2-phthalimidoacetamide, 0.69 g of hydrazine hydrate and 0.91 g of 3-methylphenyl isocyanate are used as the starting material. The product obtained is purified by chromatography on 25 g of silica (0.065-0.200 mm) contained in a column 1.7 cm in diameter [eluent: methylene chloride/ethyl acetate (80-20 by volume)], collecting 25 cm3 fractions. Fractions 12 to 23 are combined and concentrated to dryness under reduced pressure (2.7 kPa) at 40° C. After recrystallization from ethyl acetate, 0.9 g of 2-[3-(3-methylphenyl)ureido]-N-[2-oxo-2-(1,2,3,4-tetrahydro-1-quinolyl)ethyl]-N-phenylacetamide melting at 167° C. is obtained.
